Base64 tools look interchangeable until you need to do something slightly beyond plain text — encode a file, decode straight to a downloadable PDF, or handle a large payload without the page choking.
| Tool | Text encode/decode | File support | PDF-specific round trip | Runs fully in your browser |
|---|---|---|---|---|
| iLoveDevTools | Yes | Yes | Yes — dedicated PDF↔Base64 tools | Yes |
| Base64Decode.org | Yes | Limited | No | No (server round-trip) |
Beyond the standard Base64 Encoder for text, iLoveDevTools has dedicated tools for converting a PDF file into a Base64 string and back again — useful for embedding documents in JSON payloads or API requests without reaching for a script. All of it runs locally, which matters more for Base64 than most tools here, since what you're encoding is often a full file, not just a snippet of text.
Handles the basic encode/decode case cleanly and has been a reliable bookmark for a long time. It's not built for file-heavy workflows, though — there's no equivalent to a dedicated PDF conversion path.
For quick text encoding, either works. If you're regularly converting files — especially PDFs — for API payloads or storage, iLoveDevTools's file tools cover a case the general-purpose converters don't.
